EPSONProjectorUDAudio
EPSONProjectorUDAudio is a CoreAudio HAL (Hardware Abstraction Layer) driver plugin from Epson that enables macOS to recognise and route audio through Epson projectors via USB connection. HAL drivers are low-level system components that sit between the macOS audio subsystem and external audio hardware, allowing applications to enumerate and use the connected device as an audio output destination. This driver is installed as part of Epson's projector support software and is not a standalone application.
AI Recommendation
1 suggestionEPSONProjectorUDAudio is a system-level audio driver component, not a standalone app — there is nothing to update separately. The driver is installed and updated by reinstalling or updating the parent Epson projector software suite for macOS. Check the Epson support website for your specific projector model, download the latest macOS driver package, and run the installer; this will replace the old Intel-only HAL driver with a native version if one is available. If Epson has not yet shipped a native Apple Silicon build of their projector drivers for your model, contact Epson support directly to ask about native driver availability before macOS 28 arrives in September 2028 — at that point Rosetta 2 will be removed and the Intel-only driver will no longer function.
